Real Temp - New temp program for Intel Core processors

[fornowagain]

Nice work, just a question.

So a Tjmax is assumed as a fixed generic value for all chips on that particular sSpec? And the absolute values from that.

Isn't the set point (DTS=0) for PROCHOT# TCC individually calibrated per chip? Referenced to the Tjmax at workload hotspots. Meaning that each chips TCC set point could be potentially slightly different? Obviously within a range.

Just wondering about validity of absolute values. Would it be impractical to allow recalibration of the assume Tjmax within you app for advanced users? Or is the generic value so close in practise to the factory TCC to make it unnecessary. Maybe a larger sample is needed to answer that?

Yes, intel states in multiple places that desktop cpu's are individually calibrated, thus the absolute temps should be slightly different chip to chip.

Interestingly, though with two chips reading 95C Tcase when DTS=0, and based on previous chips readings, makes it likely that this chip temp difference is not much, though perhaps we should call it "average Tcc activation temp", instead of "tjmax", for desktop cpus.

Regarding individual calibration....I would not even if it were possible. Assume for arguments sake that tjmax is set at the best average tcc. Then when chip A (assume -1C difference tjmax) and chip B (assume +1C diff. from Tjmax) are both reading 70C, then both chips are exactly the same temp difference from some identified intel issue. In other words one chip can tolerate 2C more temp, but, intel has fixed it so when both chips read the same absolute temp, those temp readings mean same thing chip to chip. Why lose the beauty of that? Using DTS calibration is good, we just want to use it in the more familiar way, expressed in absolute temps, even though those "absolute temps" may in actuality be a couple degrees different chip to chip.
